REED FOR WINDING-MACHINES.

Specification of Letters Patent.

Patented June 13, 1916.

To all whom it may concern:

Be it known that I, WILLIAM M. MURPHY, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Reeds for WindingMachines, of which the followlng is a specification.

My invention relates to a reed for use upon warping or winding machines although I have shown it in connection with a machine for winding yarns on quills or bobbins, or what is generally known, as a winding quiller. Such machine comprises a frame with a number of quills or bobbins suitably mounted and rotated, the yarns coming from balls with the ends separated and led through a reed suspendedfrom overhead in front of the operator.

As heretofore constructed the reed consists of top and bottom bars between'which are fixed flat steel strips, the space between two of these strips being called a dent. The dent being very much wider than the diameter of the yarn permits knots or slubs in the through to the bobbin, such imperfections golng into the cloth.

The ob 'ect of the present invention is to construct a reed in which the strips are so set that the dent between the two strips of a pair shall be substantially the diameter of the yarn being wound, so that when a knot or slub reaches the reed it will be prevented from passing through the dent and the yarn will be broken; that is, the purpose is to break the yarn to prevent the knot or slub going through the reed and thus appearing in the cloth. To permit the operator to readily twist broken ends I widen a section of each dent through which the broken end may be threaded. The invention will be understood by reference to the accompanying drawings in whicha V Figure 1 is a vertical section of a part of a winding machine having my improved reed; and Fig. 2 a view showing the reed in front elevation. V

In the operation of the machine the yarns are taken from balls 1 around drums 2 and 3 to produce a slight friction, and the separate ends led through a reed 4 suspended from overhead in front of the operator, thence between the guide rolls 5, through the guide wires 6 to bobbins 7. The guide wires 6 are fastened to the upright rods 8, said rods being raised and lowered by cams which movement guides the yarns about the bobbins. The latter are driven from cylinders 9, all as usual and well-known.

The reed to which the present invention is directed consists of a top bar 10 and a bottom bar 11 between which are fixed fiat steel strips 12. Instead of making the dents 13 between pairs of strips wider than the diameter of the yarn, as heretofore, I set the strips so that the dent, or opening between two strips of a pair, is substantially the diameter of the yarn being wound. By so setting the strips, when a knot or slub reaches the reed it will be prevented from passing through the dent and the yarn will break. When this occurs the operator removes the imperfection thus preventing it appearing in the cloth.

In reeds as formerly constructed in which the dent is wider than the diameter of the yarn, when a yarn breaks the operator is able to thread the broken end through the dent and to twist the broken ends together. In the present construction it is impracticable to thread the yarn through the dent because of the reduced width of the latter.

To enable the operator, therefore, to readily twist broken ends together I cut out a section of the strips so as to provide spaces 14: wider than the dents. When a yarn breaks, the end back of the reed is passed through the corresponding space 141 and twisted with the end in front of the reed.

Normally the yarns run about the center of the reed and the spaces 14: may be either at the top or bottom of the reed, or any other point than that at which the yarn is normally run.

Inasmuch as the strips are so placed that or diameter of yarn; that is, each count or diameter of yarn will have a corresponding reed.
